The Lowdown
Alright, Rusty here. Let’s talk about Jaconé.
The forecast starts off with a punch. Thursday morning the 13th of August, we’ve got a solid 7ft S swell rolling in with a 12-second period, and the wind is a light NNE cross-off. It’s clean, it’s got strong energy, and it’s pumping. This is for experienced surfers only—over 5ft, so leave the foamies at home. The water temp is sitting about average for this time of year.
That Thursday holds up right through the afternoon too, with the swell even pushing 8ft and a longer 14-second period, energy ramping up. Still clean, still cross-off. This is the standout window of the whole run. Glassy mornings make for easy paddling, and that long period will wrap nicely into the point.
Friday morning the 14th gets a little wonky with a W cross-on breeze and the swell dropping to 7ft. It’s still sizable but choppy. The rating drops off. Friday afternoon stays average with a S cross-on. Not your best session.
Then Saturday morning the 15th turns it back on: offshore ENE wind at 9 mph, 8ft S swell at 13 seconds, energy strong. Clean, powerful, and set up for experienced crew. That’s your second best window—maybe even the pick if you like morning glass. Afternoon goes sideways with a risk of t-storms and howling ESE winds.
Sunday the 16th drops off in size quickly. Morning has 4ft and offshore ENE, but the energy is weak and wind is 16 mph. Not worth paddling out, really. By Sunday arvo, it’s small and messy.
From Monday the 17th through Wednesday the 19th, swell shifts to the east with short period (8 seconds or less), weak energy. Periods under 8 seconds mean junky, weak waves. A couple of windows are offshore and clean, but the swell is tiny and weak. Honestly, there’s a solid gap of several days here with no real recommendations.
Saturday the 22nd is a write-off—onshore SW wind, rain, poor conditions. Sunday the 23rd picks up a bit with a 6ft SSW groundswell at 12 seconds, but it’s onshore and choppy. Not clean.
Monday the 24th morning is worth a mention: 6ft S swell at 10 seconds, light cross-off ENE wind, moderate energy. Clean, very good conditions. That runs through Monday afternoon too. It’s not as big as that first Thursday, but it’s solid and clean for intermediates and above. Tuesday the 25th morning is still clean with offshore wind and 5ft, but it’s dropping.
The rest of the run into late August gets smaller, shorter period, and weaker energy. Nothing to get excited about. Crowds are possible at Jaconé on the standout days—it’s a consistent spot, so it’ll draw people.
So, your best bets are Thursday morning the 13th of August (7ft S, 12s, NNE cross-off, clean, strong energy), and Saturday morning the 15th of August (8ft S, 13s, offshore ENE, clean, very strong energy). Everything else is either too small, too windy, or too choppy to go out of your way for.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
